If a spell has Repeat twice (e.g., Hard Bargain with Temporal Portal) and you control 2 Ezreals, does each Ezreal reduce each instance of the Repeat cost separately, or do they reduce the total cost once?

Ruling: Each Ezreal reduces each optional additional cost paid separately. With 2 Ezreals and paying Repeat twice on Hard Bargain, the total cost would be 4 energy (2 base + 1 for first Repeat + 1 for second Repeat).

Sequence:

• Pay the base cost of the spell (2 energy for Hard Bargain)
• For each Repeat cost paid, apply the Ezreal reduction separately
• First Repeat: 2 energy - 1 (from Ezreal) = 1 energy
• Second Repeat: 2 energy - 1 (from Ezreal) = 1 energy
• Total: 2 + 1 + 1 = 4 energy

Nuances:

• Each optional additional cost is tracked as a discrete Boolean (paid or not paid) for modalizing the finalized effect
• An alternative interpretation exists where all optional costs are aggregated before applying reductions, which would result in only one reduction total
• The ruling provided is the recommended interpretation but acknowledged as not 100% certain from the rules text alone
